Hi! My name is Ms. Hoskins. Please join me while I travel to Maryland to study Climate Change and Fragmented Forests!

Math and Science go Together

This short video clip will show how scientists map out the forest floor utilizing X and Y coordinates.

Are you going to use the grid as a sample or are you only concentrating on that particular area? If you are using it as a sample how large is the actual area? And how large is the sample area?

So Ms. Hoskins how are you doing that with out graph paper? Is it hard? How do you know exactly which lines represent the X axis and which Y axis? Do all the leaves make it difficult to know what you are doing?

The sample we did yesterday was 10 meters by 10 meters. The group beside us did a 10 by 10 meter square. In all we did 12 10 by 10 meter squares. Another team will continue until all 100 ten meter squares are done! What were we doing? Measuring and tagging all the trees in our 10 by 10 square. We lay out this huge meter measuring tape for the X axis and one for the Y axis. After we tag and measure a tree, we have to write down the coordinates of the tree. For example the first tree I tag measures 10.2 meters in circumference and is located at 2.4 meters on the Y axis and 5.6 on the X axis. Its tag number is 10024. This way you can always find this tree.

I like not having graph paper because the area we are griding is so large and the tape measure is 100 meters long, so we do no have to be 100% accurate when we are trying to measure trees in water. We have two tape measures, one for the X axis and one for the Y axis. We do our area and the other teams do all the areas around us so when we are done, we have completed a section of the forest dozens of meters long and dozens of meters wide.
